Commercial Plumbing Installation & New Construction

Commercial plumbing installations require careful coordination, correct system sizing, and strict adherence to code. We support new builds, expansions, tenant improvements, and renovation plumbing for commercial spaces, with systems designed to meet commercial demand.

We also install commercial-grade fixtures and appliances and confirm proper water supply and drainage performance, as well as safe connections, before the space is turned over for use.

New Construction Plumbing

New construction plumbing includes rough-in and full system installations for commercial properties. We coordinate with builders, project managers, and inspectors to ensure layouts support flow demands, safety, and long-term performance. Installations are verified through pressure and leak checks, along with confirmation of drainage and venting, before close-up.

Commercial Water Heater Installation

Commercial water heater installation covers both tank and tankless systems. We plan capacity based on business usage, peak demand, and recovery needs to help ensure consistent hot water without system strain. We also verify connections, venting requirements, and safe operation before the system is put into daily service.

Boiler Installation

Boiler installation services support hydronic and commercial heating systems. Proper sizing, safety controls, and compliance are critical to reliable operation and energy efficiency. We confirm correct connections, control response, and stable system performance before we consider the job complete.

Commercial Drain, Sewer & System Cleaning

Flow restrictions and blockages can disrupt operations quickly. We provide regular inspection and cleaning that helps prevent backups, slow drains, odors, and avoidable shutdowns, especially in high-use restrooms, kitchens, and service areas.

Drain Repair

Drain repair prevents sanitation concerns and operational disruptions by correcting damaged sections, compromised connections, or drainage issues at the source. We isolate the problem area, complete targeted repairs, secure fittings, and verify proper flow to reduce the likelihood of repeat problems.

Sewer Inspection

Sewer inspection services use camera technology to locate the problem area and identify the cause of drainage issues, such as buildup, offsets, deterioration, or root intrusion. This helps confirm the right solution before repairs or deeper cleaning.

Sewer Drain Cleaning

Sewer drain cleaning clears buildup and obstructions from main lines, drains, and sewer lines to reduce backups and unexpected shutdowns. This is especially important for restaurants, multi-unit properties, and facilities where recurring clogs can interrupt daily operations.

Commercial Pipe & Water Line Services

Commercial plumbing repairs require a fast response and an accurate diagnosis to limit downtime and property damage. We isolate the issue, identify the failure point, and complete repairs with durability and access considerations in mind.

Water Leak Repair for Pipes

Pipe water leak repair in San Rafael, CA, addresses active leaks in walls, ceilings, mechanical rooms, and service areas. We locate the leaking pipe, stop water at the appropriate shutoff, complete the repair at the failure point, and verify stable pressure and leak-free performance before we leave.

Pipe Repair

We address damaged, corroded, or failing pipes. We isolate the affected line, access the problem area, remove the compromised pipe, and complete a secure pipe repair using compatible materials and fittings.

Grease Trap Services for Commercial Kitchens

In busy kitchens, grease cools, thickens, and collects in the trap and lines. If the trap is undersized, installed poorly, or not maintained on schedule, this causes slow drains, odors, and backups that disrupt service.

Our commercial plumbing company installs and maintains grease traps with a focus on practical performance: proper sizing for kitchen demand, correct placement for access, and clean connections that keep flow moving and reduce grease carryover into the sewer line.

Grease Trap Installation

Grease trap installation starts with choosing the correct size and location for your kitchen’s usage and layout. We confirm proper inlet and outlet alignment, secure connections, and accessible placement for routine service. After installation, we run water to verify flow through the trap and check for leaks at fittings and joints.

Grease Trap Cleaning

Grease trap cleaning is more than scooping the top layer. We remove built-up grease and solids, clear the trap so it can separate properly again, and check for signs of problems like restricted flow, heavy carryover, or worn seals. Routine cleaning helps reduce odors, slow drainage, and grease-related backups that can shut down sinks and floor drains.

Keep your kitchen moving without surprise backups. Reach our commercial plumbing contractor at 415-755-0626.

Preventive Plumbing System Maintenance

Preventive plumbing system maintenance in San Rafael helps reduce unexpected failures and extend the lifespan of commercial plumbing infrastructure. Scheduled inspections identify wear, buildup, and developing issues before they cause downtime.

Maintenance programs are especially valuable for facilities with continuous use or regulatory requirements. This may include routine checks of drainage performance, early signs of leaks, and system condition in restrooms, kitchens, and mechanical areas.

Schedule preventive maintenance by calling 415-755-0626.
